Duplicate name exists on the network?

We have one unusual issue in one of our workstation here.

Every morning after the PC is idle for a very long time, it will disconnect all of its connection in the Printer, File and exchange servers. We already change the setting to never hibernate, monitor, hard drive always on. Ethernet power save is off.

I tried to ping the printer server and I’m getting a response to it (Printer, File and exchange servers) but if I will browse the server by using it will say “You were not connected because a duplicate name exists on the network”.

Restarting the workstation will solve the issue but restarting every morning makes my user annoyed.

Other Technical details please find below.

Workstation

·         Windows XP Prof SP3

·         Dell 760 all hardware in normal condition

·         Office 2007

Servers

·         Windows Server 2008

Any feedback on this would be highly appreciated.

Thanks. We'll let you know when a new response is added.

Check that there is not a problem with the DNS Cache.
Also, do you have entries in the HOSTS file? this may have an incorrect entry on one or more of the machines in your network.

Also, did you use SYSPREP or cloning to create your PC’s?

    Our naming convention on our PC are the service tags... there is no way we could have duplicate names... But we tried that but totally unique name... We also thought about changing the name but we will break our naming convention of our client PC if we do that.. Probably if we really can't find any solution to it.... The weird thing is after restart everything is ok like nothing happens...

    Try this to check each computer name and what other systems think the computer names are: On each system run "nbtstat -n" On another system run "nbtstat -a IPAddress" for each of the problem systems

    Give the machine a new SID and re-name it that should do it. Use this tool http://technet.microsoft.com/en-us/sysinternals/bb897418.aspx

    @RickC I've checked the two machines SID and they have different SID SID for \Machine1: S-1-5-21-776561741-1580436667-1417001333 SID for \Machine2: S-1-5-21-682003330-1659004503-2147069159

    sorry for slow reply, just to add, last time I had the same issue too. i formatted the computer, and wanted the pc to rejoin the domain. but upon rejoining, they say the name already exist in the network. Before that i even remove the pc from the OU...I could not continue as I had already resign and assign the task to another person. but from what i read, they mention that it at times can be the problem with AD or DNS that does not refresh thats why the system always clashes...but since I left the company, i didnt have anymore platform to test....

    @ Jinteik My situation is somehow different. The machines are doing good before, then suddenly this happens when users start to builds up.
